Quick release N gives way to Methylene Urea followed by a final release from the organic based element. Slow release potash from Kali vinasse helps regulate the water, as well as the intake and movement of nutrients around the plant. This is essential to reduce plant stress and enhance drought resistance. GSR Tri-Phase is perfect for sports fields, golf fairways, golf tees and all amenity areas. 

  • 16-20 week release period
  • Mini-granular for quick dispersal in to soil
  • Phased release ensures uniform feeding across the period of use
  • Slow release potash aids plant health and drought resistance

The spreader settings are guidelines only. The spreader should be calibrated prior to application to ensure accuracy. The spreader settings are based on a walking speed of 5km/hour. Walking faster or slower than 5km/hour will alter the speed width and application rate. Exact rates are dependent upon the spreader itself and the accuracy of the person operating it.
